This one should be __init rather than __cpuinit, right?  As written, I get:


WARNING: vmlinux.o(.cpuinit.text+0x824): Section mismatch in reference
from the function xstate_enable_boot_cpu() to the function
.init.text:__alloc_bootmem()
The function __cpuinit xstate_enable_boot_cpu() references
a function __init __alloc_bootmem().
If __alloc_bootmem is only used by xstate_enable_boot_cpu then
annotate __alloc_bootmem with a matching annotation.

[No need to resend the patch, but if either Suresh or Robert could ACK
this change I'd appreciate it.]
